Abstract

Cantharophily is reported for the first time in a Brazilian asclepiad, involving the mylerid Astylus variegatus and the nectariferous flowers of Oxypetalum banksii, a plant mainly pollinated by wasps. The use of nectar as food by A. variegatus, considered pollinivorous and granivorous, is also novel. The mutual interaction described here is an example of a plant-pollinator interaction with generalist insects visiting a plant with a specialized pollination system. It’s also temporary and occasional and, therefore, is often overlooked in studies of plant-pollinator interactions. In this study, we found that the casual meeting between O. banksii and A. variegatus was a key event for the reproduction of both.
